Chapter 8

Fundamental UML Behavioral Modeling

Abstract

This chapter introduces some fundamental UML constructs for modeling system behaviors. UML use case diagrams capture the scope of functional requirements of a system from the users’ perspective. A UML sequence diagram maps out a course of object interactions arranged in a time sequence. UML activity diagrams are used for modeling the control flows and data flows of a business process, an engineering workflow, or a procedural computation.
